resulting from the recoil of elastic elements in the vessel walls as the smooth muscle walls relax. Vascular resistance is owed largely to the arterioles of the systemic circulation. Arteriole resistance regulates blood flow to the tissues downstream. In addition to this arteriole resistance (in combination with the cardiac output) regulates the systemic arterial pressure. Intrinsic (local) mechanisms: In tissues with low tolerance of ischaemia (inadequate blood flow)‚ such as the brain and heart‚ intrinsic

thickening of the pulmonary arterial wall causing a state of permanent vasoconstriction. In addition‚ the pulmonary vasculature that produces the body’s natural vasodilators becomes impaired therefore further contributing to pulmonary vascular remodeling‚ systemic hypoxia‚ and pulmonary thrombosis. All these‚ he said‚ could cause an elevated mean PA pressure and eventually a state of permanent pulmonary hypertension.

It also induces pleasure and reduce anxiety‚ along with stress. Nicotine is one of the many chemicals in tobacco. When inhaled‚ the nicotine diffuses into the pulmonary blood and enters the systemic circulation‚ quickly reaching the brain. When in the brain the nicotine binds to the acetylcholine receptors (nAChRs) (Rosenthal‚ D. G et al. 2011). An important neurotransmitter is dopamine‚ which is critical to the acute reward pathways associated with

P4- Explain the physiology of two named body systems in relation to energy metabolism in the body. Energy is the strength and ability that is required in order to perform physical or mental activities. There are different forms of energy these consist of: magnetic‚ kinetic‚ heat‚ light‚ gravitational‚ chemical‚ sound‚ electrical‚ elastic and nuclear. The law‚ conservation of energy states that the total amount of energy within a system remains constant at all times‚ although energy within the system

Academy of Neurology that high blood pressure during middle age may raise the risk of cognitive decline later in life. According to Medilexicon’s medical dictionary‚ hypertension means "High blood pressure; transitory or sustained elevation of systemic arterial blood pressure to a level likely to induce cardiovascular damage or other adverse consequences." The normal level for blood pressure is below 120/80‚ where 120 represents the systolic measurement (peak pressure in the arteries) and

Discuss the role of energy in the body and analyse how those two body systems interrelate to perform a named functions. For distinction analyse Energy it is the ability to do work. Energy cannot be destroyed but it can be changed to another form. Without energy we would not be able to growth or move. To stay alive we need regular and permanent supply of energy or else we
